This is a very educating talk by Tom Holland about the origins of Islam. Tom Holland is the famous English historian and writer. He was educated at Queens College Cambridge where he obtained a double First in English and Latin.
I find the talk informative and useful.
Exceptthe question and answer session. He messes up on 'jizya'.
I am out of time. I hope to comment on this later.
Especially for Muslims, this video will be a useful 45 minutes.
